78-6511-05
Preface
Audience
The Catalyst 2900 Series XL and Catalyst 3500 Series XL Software
Configuration Guide is for the network manager responsible for configuring the
Catalyst 2900 series XL and Catalyst 3500 series XL switches, hereafter referred
to as the switches. Before using this guide, you should be familiar with the
concepts and terminology of Ethernet and local area networking.
Purpose
This guide provides information about configuring and troubleshooting a switch
or switch clusters. This guide also provides information about configuring the
Cisco 575 Long-Reach Ethernet (LRE) customer premises equipment (CPE). It
includes descriptions of the management interface options and the features
supported by the switch software.
Use this guide in conjunction with other documents for the following topics:

Requirements—This guide assumes you have met the hardware and software
requirements and cluster compatibility requirements, as described in the
release notes.

Start up information—This guide assumes you have assigned switch IP
information and passwords by using the setup program, which is described in
the release notes.

Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide
78-6511-05

Cluster Management Suite (CMS) information—This guide provides an
overview of the CMS web-based, switch management interface. For
information about CMS requirements and the procedures for browser and
plug-in configuration and accessing CMS, refer to the release notes. For CMS
field-level window descriptions and procedures, refer to the CMS online
help.

Cluster configuration—This guide provides information about planning for,
creating, and maintaining switch clusters. Because configuring switch
clusters is most easily performed through CMS, this guide does not provide
the command-line interface (CLI) procedures. For the cluster commands,
refer to the Catalyst 2900 Series XL and Catalyst 3500 Series XL Command
Reference.

CLI command information—This guide provides an overview for using the
CLI. For complete syntax and usage information about the commands that
have been specifically created or changed for the Catalyst 2900 XL or
Catalyst 3500 XL switches, refer to the Catalyst 2900 Series XL and
Catalyst 3500 Series XL Command Reference.
Note
This guide does not repeat the concepts and CLI procedures provided
in the standard Cisco IOS Release 12.0 documentation. For switch
features that use standard Cisco IOS Release 12.0 commands, refer to
the Cisco IOS Release 12.0 documentation on Cisco.com for
additional information and CLI procedures.
